OK well you have 2 different error codes going on. First the ICE code will always show when the water in the spa is at a temperature of 40 degrees or less. Now with that said the DRY code is indicating that the heater is running in dry mode meaning no water flow through the heater tube. You may just have an air lock in the pump. Open the cabinet up and locate the union on the front of the pump that supplies water to the heater and loosen the union (Breaker Off) let some water leak out and re-tighten the union then power the breaker back up and let spa turn on. Repeat this process as needed until air purges out and you get a good flow of water through jets then the DRY code should go away.
